Step 11 - Review the Calibration Results

1. When the calibration of the TESASTAR-R / HR-R Probe Changer is complete, select the Ports tab in the Probe Changer dialog box (Edit | Preferences | Probe Changer). The calibration information now exists for the location of each calibrated port. For example:

PC-DMIS Message

All measurement is now complete. Please reconnect the probe used to measure the ports and then click OK.

2. When you view the results, look for the following. Any significant deviations from these expectations may be due to a bad hit.

- The probe changer must be aligned parallel to either the X or the Y axis of the CMM.

- The Z values for all regular ports should be nearly the same and the Z for all HD ports should be nearly the same. However, the Z for regular ports will not be the same as the Z for HD ports.

When you use an HD wrist, you should remove the datum sphere from the rack after calibration if complete. This prevents collisions when using the two adjacent ports for tool changes.

How a LOADPROBE command works with the TESASTAR-R / HR-R Probe Changer:

1. During measurement routine execution, the probe entities that you added to each port are automatically picked up from the port whenever PC-DMIS executes a LOADPROBE command for that probe.

2. Before picking it up, the probe body moves to the mount point and then into the empty port to drop off the current probe.

3. The rack's keys rotate to the release position. The current probe remains in the port while the probe body lifts away to detach.

4. The probe body moves over the load position above the port that contains the probe.

5. The probe body moves down onto the new probe. The keys again rotate to automatically engage the new module.

6. The probe body moves back out of the port and over to the rack’s mount point.

7. The CMM continues to measure the part with the newly loaded probe.

The probe change cycle varies slightly from the steps described above for HD ports and extensions.
